Lex CloakSignatures and handwriting
Lex Cloak scans for handwritten signatures automatically after each document scan, marking what it finds for redaction. You can turn this on or off under Settings, Detection, Auto-detect signatures, and run the scan any time from Signatures in the More menu. Signature detection is best-effort, so check the results by eye and use draw mode to cover anything it missed.
How signature detection works
Signatures are different from typed identifiers. They carry weight in legal, medical, and government workflows, and a forgotten one is the kind of false negative Lex Cloak exists to prevent. Any kind of document can carry a signature, so Lex Cloak runs the signature scan automatically right after each document scan and marks what it finds for redaction, so you do not have to remember to start it. You stay in control: every finding is a proposed box you can review and turn off, and you can change this default under Settings, Detection, Auto-detect signatures.
Running or re-running the scan
- The scan runs on its own right after the main document scan. To run it again, or if you turned the automatic scan off, click Signatures in the More menu. It is disabled until the document is scanned.
- Each finding shows up as a proposed redaction box, in the same colour as the other uncertain matches.
- Review each finding by eye. Use the page navigation keys to step through the document quickly. For anything you want to redact, leave it on. For anything you want to keep visible, turn it off.
- Where the scan missed something, hold Shift and drag to draw a redaction box. See draw a redaction over anything.
The pre-download checklist warning
When the scan finds signatures, the pre-download checklist shows a Signatures found warning. This is a reminder to confirm that every signature has been reviewed and either covered or deliberately left visible, not a block. See the per-warning reference on the pre-download checklist.
For high-stakes documents, the best approach is to combine the scan with a manual page-by-page review. The scan catches the obvious cases. Your eye catches the ones the scan could not.
